IMPROVEMENT IN BROW-BANDS FOR BRIDLES.

Specification forming part of Letters Patent N o. 156,435, dated November 3, 1874; application tiled October 9, 1874.

To all whom t may concern:

Be it known that I, FRANZ MEINBERG, of New York city, in the State of New York, have invented certain'lmprovements relating to Brow-Bands for Bridles, of which the following is a specification:

The construction set forth in the patent issued to me December 24, 1872, is a desirable one, but I have succeeded in improving upon it.

I have devised the employment of two or more springs peculiarly applied together within the leather, and make a very efficient and desirable junction thereof, with a leather loop at the ends. The loop is exible and centrally secured between the two parts of ,my compound spring, while the main band is highly elastic and tough, and will stand a large amount of hard usage, and a much thinner facing metal may serve within the concave front.

The accompanying drawings'form a part of this specification, and represent what I consider the best means of carrying out the inf vention. v

Figure l is a general perspective view, representing the front band complete. Fig. 2 is a cross-section of the same 5 and Fig. 3 is a horizontal section through a portion, showingthe junction of the end loops with the springs. l

The additional figures are cross-sections representing modifications.

Similar letters of reference indicate like parts in the figures. i

M and N are two matched concave springs, fitted one within the other, and properly curved, as shown. They may be made of steel or semi-steel, or hard brass; but I have made Very successful ones of hard iron, giving a preference to the brands known as Swedes. A covering of patent-leather, or other suitable leather, B, envelops the two, with the joint or abutting edges in the concave front. A narrower ornamental band, D, of thin brass, silver-plated, lies inthe trough-like front.

The ends of the springs M N are opened apart, as represented, and receive the chamfered ends of stout leather loops A1 A2. Ef-

cient rivets, E, being inserted through the decorative facing material D, and also through the covering B, the spread ends of the springs M N, and through the inclosed material of the end loops A1 A2, the whole is very strongly and permanently secured. The outside washer or clinch-ring on the rivet E may be decorative.

The construction shown in my patent of December, 1872, is rigid at the junction of the looped ends with the body, where I find that rigidity is not desired. Its main body is not sufciently elastic. I have, in working the invention, endeavored to remedy this latter evil by giving much strength to the ornamental front bandmD, but this, being an exposed piece, requires to be of incorrodible material, and greatly increases the expense.

My present plan, by employing two i11- closed springs, matched together so as to be jointly concave or trough-like, set with the proper curvature, gives great strength and lightness, with sli ghtV cost for the spring material, allows the employment of a very thin facing material, and affords llexible loops at the ends very efliciently secured, not on one side of a single spring, but within and between the two nicely-covered springs M and N.

I can vary the form of the springs within wide limits, so long as I preserve the general concave character, and its compound construction of separate springs lying together, and nicely covered, with the cavity in front receiving the front band. I can make the front spring narrower than the back. I prefer to make it with a greater curvature than the back spring, so as to lit-perfectly in its concave interior; but I can, if preferred, employ a quicker curvature near the upper and lower edges of the back spring, and have the front one narrower, and nearly ilat, so as to be embraced within it.

Two rivets may be employed to secure the flexible end loops within the compound spring at each end, if preferred 5 but I do not deem it necessary. The compound spring may be made in three or four thicknesses, if preferred.

I claim as my inventionl. The compound brow-band spring M N, formed in two or more separate thicknesses of sheet metal, curved and concave, and adapted to serve as and for the purposes herein speci- In testimony Whereof'I have hereunto set fied. my hand in the presence of two subscribing 2.
